How to Date Antique Furniture Without an Expert: The Signs That Wood and Construction Reveal

Antique furniture tells its own story — if you know how to read it. The wood, the joinery, the hinges, the fasteners: every element places a piece of furniture in a time period. No instruments needed, just attention.

The Wood: Species and Treatment

Before the 18th century, oak, walnut, and fruitwood were the dominant wood species in European furniture. Mahogany entered the picture in the early 18th century via England. Rosewood, palisander, and exotic woods rose in popularity during the Empire period and later.

Look at the inside of drawers and the back of cabinets: the carcass (the construction itself) is often made of a different, cheaper wood than the exterior. That combination tells you a lot.

Hand-sawn wood — recognizable by slightly wavy saw marks — dates from before 1850. Machine-sawn wood shows straight, uniform marks. This isn’t an absolute dating method, but it’s a strong indicator.

Joints: The Proof in the Corners

The way two pieces of wood are joined is one of the most reliable dating indicators.

• Hand-cut dovetails are asymmetrical — each tail is slightly different. Machine-cut dovetails are identical and uniform. This distinction separates handcraft (before ~1860) from industrial work.
• Wooden pegs and pins as fasteners are older than metal screws.
• Round wooden plugs that protrude slightly above the surface indicate shrinkage of old wood — a good sign.

Hinges and Hardware

Hand-forged iron hardware — with small irregularities and an asymmetrical character — dates from before the Industrial Revolution. Cast brass hinges emerged in the 18th century. Stamped hardware is 19th century or later.

Also look at the screws: hand-cut screws have an asymmetrical slot and a pointed tip. Machine-made screws are uniform. Well into the 19th century, screws were still cut by hand.

Patina and Wear: Real vs. Artificial

Real wear is logical: where hands touch, where doors make contact, where drawers slide — that’s where the finish is worn. This wear is consistent with how the piece was used.

Artificial “antiquing” is random or too uniform. Wear in places that were never touched, surfaces that are too evenly worn — these are warning signs.

The inside of drawers in an authentically old piece of furniture has a specific smell — dry, slightly musty, old wood. Modern furniture smells different. It sounds trivial, but it’s a real indicator.

What Does This Mean for Value?

A piece of furniture that shows all signs of authenticity — handcraft, logical wear, correct wood species for the period, consistent hardware — is fundamentally different from a reproduction, even if they look identical in photos.

Reproduction antique furniture isn’t worthless — but it’s not antique, and the price should reflect that.
